About this Collection

The Directory of U.S. Newspapers in American Libraries is a searchable index of newspapers published in the United States since 1690. This directory can help identify what titles exist for a specific place and time, and how to access them. The Library of Congress does not hold all titles included in this Directory. For a detailed overview of the Directory, search tips, and FAQs, please consult the Directory of U.S. Newspapers in American Libraries: A Guide for Researchers.

Previously known as the United States Newspaper Directory and included in the Chronicling America: Historic American Newspaper online collection, the Directory of U.S. Newspapers in American Libraries online collection is derived from the library catalog records primarily created by state institutions during the United States Newspaper Program (USNP), 1982-2011. The USNP was funded by the National Endowment for the Humanities (NEH) and supported by the Library of Congress to sponsor state-level projects to locate, describe (catalog), and selectively preserve (via treatment and microfilm) historic newspapers in every state, published from 1690 to the present. Under this program, each institution created machine-readable cataloging (MARC) via the Cooperative ONline SERials Program (CONSER) for its state collections, contributing approximately 140,000 bibliographic descriptions and 600,000 library holdings records to the Newspaper Union List, hosted by the Online Computer Library Center (OCLC). These data were eventually combined with other databases into the global WorldCat cooperative database. While the data in the Directory of U.S. Newspapers in American Libraries mirrors what is also available in OCLC WorldCat, the directory provides an alternate interface to this information, tailored to searching newspaper records and available as its own dataset.

While the USNP is no longer an active program, the Library of Congress continues to update the Directory of U.S. Newspapers in American Libraries on a regular basis in order to include any changes made to the newspaper records. The Library of Congress periodically harvests all CONSER-authenticated U.S. newspaper records from the WorldCat service using the Open WorldCat API (Application Programming Interface) and, where possible, matches them up with USNP-created library holdings information also held separately by OCLC.

For questions or information on updating bibliographic records, contact a local CONSER member or the National Digital Newspaper Program at the Library of Congress.
